Rose plant 74-1489-2

ABSTRACT

A hybrid tea rose variety having an upright plant habit with dark green, glossy foliage, red-tipped yellow buds, and fully double open flowers.

This present invention relates to a new and distinct variety of roseplant of the hybrid tea class which was originated by me by crossing thevariety Precilla, U.S. Plant Pat. No. 3,726, with the variety Sunshine,U.S. Plant Pat. No. 3,791.

The primary objective of this breeding was to produce a new rose varietyof a vigorous, prolific, upright plant producing yellow blooms of goodcolor, form, and substance. This objective was substantially achievedalong with other desirable improvements as evidenced by the followingunique combination of characteristics which are outstanding in the newvariety and which distinguish it from its parents as well as from allother varieties of which I am aware:

1. An upright plant habit, bearing dark green, glossy foliage.

2. Bud of a rich yellow color tipped with red.

3. Fully double (40 petals) open flowers fading only slightly uponaging.

Asexual reproduction of this new variety by budding, as performed atWasco, Calif., shows that the foregoing characteristics and distinctionscome true to form and are established and transmitted through succeedingpropagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor in terminology in accordance with The Royal Horticultural SocietyColour Chart except where ordinary dictionary significance of color isindicated.
